Wirelessly actuated cover for a structure

ABSTRACT

A cover is configured to selectively engage with a portion of a structure in response to receiving a wireless electrical power signal at a receiver antenna of the cover from a wireless power source located in an outside environment, to separate a first environment on a first side of the cover from a second environment on a second side of the cover opposite the first side. In response to wirelessly receiving the electrical power signal, a fastening subassembly of the cover changes from a secured mode configured to inhibit opening a cover body with respect to the structure, to an unsecured mode configured to facilitate opening the cover body with respect to the structure. This in turn allows the cover to be matingly engaged with a portion of the structure to form a smooth continuous surface, without any exposed fasteners on the exterior side of the cover.

This application is a divisional of co-pending U.S. patent applicationSer. No. 15/489,222, filed on Apr. 17, 2017, entitled “WIRELESSLYACTUATED COVER FOR A STRUCTURE,” which is hereby incorporated herein byreference in its entirety.

TECHNICAL FIELD

Embodiments relate to a cover for a structure, and more particularly toa wirelessly actuated cover for a structure.

BACKGROUND

Conventional covers have many different applications. In someapplications, such as a cover for an access opening in an aircrafthousing for example, it may be desirable to provide an exterior surfacethat is as smooth and continuous as possible, to improve aerodynamic andstealth capabilities of the aircraft housing, for example. However, onedrawback of conventional covers is that a number of exposed conventionalfasteners may be required to secure the cover to the housing. This leadsto a less smooth and less continuous surface, which may in turnadversely impact the aerodynamic and stealth capabilities of theaircraft housing, for example. Thus, there is a need for a cover thatdoes not have these drawbacks.

Embodiments relate to a cover for a structure and, more particularly, toa wirelessly actuated cover for a structure. In one embodiment, a coverincludes a cover body configured to selectively engage with a portion ofa structure to separate a first environment on a first side of the coverfrom a second environment on a second side of the cover opposite thefirst side. The cover is configured to be selectively secured and/orunsecured with the structure in response to receiving a wirelesselectrical power signal at a receiver antenna of the cover, from awireless power source located in an outside environment. In response towirelessly receiving the electrical power signal, a fasteningsubassembly of the cover changes from a secured mode configured toinhibit opening the cover body with respect to the structure, to anunsecured mode configured to facilitate opening the cover body withrespect to the structure. This in turn allows the cover to be matinglyengaged with a portion of the structure to form a barrier between thefirst environment and the second environment, without any exposedfasteners on the exterior side of the cover, while maintaining theability for a user to selectively open the cover from the exterior firstside of the cover.

Before discussing the embodiments, a conventional cover 100 according tothe prior art will be described with respect to FIG. 1. The conventionalcover 100 includes a cover body 102 configured to engage a structure104, such as, for example, an aircraft housing. The conventional cover100 has a cover exterior side 106 configured to form a continuoussurface with a structure exterior side 108 of the structure 104. In manyapplications, such as a carbon fiber aircraft housing for example, it isdesirable to provide an exterior surface that is as smooth andcontinuous as possible, to improve aerodynamic and stealth capabilitiesof the aircraft housing, for example. Thus, it is desirable for thecover exterior side 106 and the structure exterior side 108 to be formedwithin precise tolerances in order to minimize a seam 110 therebetween.However, a number of conventional fasteners 112 are required to securethe cover body 102 of the conventional cover 100 to the structure 104.While these conventional fasteners 112, such as bolts for example, maybe recessed, the conventional fasteners 112 are nevertheless exposedwith respect to the cover exterior side 106 and the structure exteriorside 108, and may still adversely impact the aerodynamic and stealthcapabilities of the aircraft housing, for example. This in turn mayrequire secondary processing, such as adding a protective coating overthe entire cover exterior side 106, structure exterior side 108 andexposed conventional fasteners 112, to provide a sufficiently smoothcontinuous surface. This approach may also have the additional drawbackof making removal and replacement of the conventional cover 100 moredifficult, time-consuming, and expensive, because accessing theconventional fasteners 112 and removing the conventional cover 100 mayrequire first removing a portion of the protective coating, andreapplying the protective coating after re-securing the conventionalcover 100 to the structure 104. Repeated removal and replacement of theconventional fasteners 112 may also damage portions of the conventionalcover 100 or structure 104, which may be formed from easily damagedmaterials. Thus, there is a need for a cover for a structure that doesnot exhibit these drawbacks.

In this regard, FIG. 2 illustrates a wirelessly actuated cover 114having a cover body 116 for selectively engaging with a portion of astructure 118 according to an embodiment. In this embodiment, the cover114 is an access panel and the structure 118 is part of an aircrafthousing, but it should be understood that these and other embodimentsmay be used in any number of different applications. The cover body 116of the cover 114 has a first side 120, e.g., an exterior side, and asecond side 121, e.g., an interior side, opposite the first side 120.The cover body 116 in this embodiment is configured to matingly engagewith an exterior side 122 of the structure 118 to separate anenvironment on the first side 120 of the cover body 116 from anenvironment on the second side 121 of the cover body 116. The cover body116 in this example is configured to matingly engage with an aperture126 in the structure 118. In particular, a perimeter edge 124 of thecover body 116 engages with a recessed rim 128 extending around theaperture 126 of the structure 118, with the perimeter edge 124 of thecover body 116 matingly engaging with an interior perimeter edge 130extending around the aperture 126.

As will be discussed in greater detail with respect to FIGS. 3A and 3Bbelow, the cover 114 is configured to be selectively secured over theaperture 126 of the structure 118 without requiring any exposedfasteners on the first side 120 of the cover body 116 or the exteriorside 122 of the structure 118. Instead,

FIG. 2 illustrates a cover removal tool 132 configured to selectivelysecure and/or unsecure the cover 114 with respect to the structure 118using a wireless power signal, to facilitate opening and closing thecover 114. As will be described in greater detail with respect to FIG.4, the cover removal tool 132 includes one or more handles 134, whichmay be grasped by a user, and an actuation button 136 or other actuationmechanism for causing the cover removal tool 132 to provide a wirelesselectrical power signal to the cover 114, thereby allowing the cover 114to be secured to or removed from the structure 118.

Referring now to FIGS. 3A and 3B, detailed views of the cover 114 areillustrated. As shown in FIG. 3A, the cover 114 matingly engages withthe structure 118 to form a smooth continuous surface, without anyexposed fasteners on the first side 120 of the cover body 116. Referringnow to FIG. 3B, the second side 121 of the cover body 116 includes aplurality of fastening subassemblies 138 arranged around the cover body116 proximate the cover body perimeter edge 124. Each of the fasteningsubassemblies 138 are coupled to the second side 121 and has a securedmode configured to inhibit opening the cover body 116 with respect tothe structure 118, and an unsecured mode configured to facilitateopening the cover body 116 with respect to the structure 118. In thisembodiment, a plurality of electrical traces 140 connect each fasteningsubassembly 138 to a receiver antenna 142 coupled to the cover body 116.In this embodiment, the cover body 116 may be further configured to forman airtight and/or a watertight seal between the second side 121 of thecover body 116 and an outside environment that is outside the first side120 of the cover body 116 in response to the cover body 116 matinglyengaging with the structure 118 and the fastening subassembly 138 beingin the secured mode. The cover 114 may be configured to maintain theairtight and/or watertight seal up to at least a predetermined maximumpressure differential between the second side 121 of the cover body 116and the outside environment. For example, in one embodiment, apredetermined maximum pressure differential for an airtight seal for anaircraft may be up to a 7 pound per square inch (PSI) pressuredifferential or more between the second side 121 of the cover body 116and the lower pressure outside environment. In another embodiment, apredetermined maximum pressure differential for a watertight seal for asubmersible vehicle may be up to a 15 PSI pressure differential or morebetween the second side 121 of the cover body 116 and the higherpressure outside environment.

In this embodiment, the receiver antenna 142 is disposed on the secondside 121 of the cover body 116, but it should be understood that thereceiver antenna 142 may alternatively be disposed within the cover body116, so long as the receiver antenna 142 is electrically connected tothe plurality of fastening subassemblies 138. The receiver antenna 142is configured to wirelessly receive an electrical power signal from awireless power source, such as the cover removal tool 132 of FIG. 2, forexample, located in an environment on the first side 120, e.g., theexterior side, of the cover body 116. Each fastening subassembly 138 isconfigured to receive the wireless power signal from the receiverantenna 142 and change from a secured mode to an unsecured mode inresponse to receiving the wireless electrical power signal from thereceiver antenna 142. In the secured mode, each fastening subassembly138 is configured to inhibit opening the cover body 116 with respect tothe structure 118. In this embodiment, the fastening subassemblies 138are biased toward the secured mode and, in the absence of receiving theelectrical power signal from the receiver antenna 142, the fasteningsubassemblies 138 are configured to remain in the secured mode, i.e., nopower is required to maintain the fastening subassemblies 138 in thesecured mode.

In response to receiving the electrical power signal from the receiverantenna 142, the fastening subassemblies 138 are changed to theunsecured mode, in which the fastening subassemblies 138 are configuredto facilitate opening the cover body 116 with respect to the structure118. In this embodiment, the fastening subassemblies 138 are furtherconfigured to disengage from the portions of the structure 118 inresponse to receiving the electrical power signal from the receiverantenna 142, in order to allow the cover 114 to be removed from thestructure 118, e.g., by receiving the electrical power signal from thecover removal tool 132 of FIG. 2. Because the cover 114 in thisembodiment does not have any other connections to the structure 118,e.g., electrical wiring, this also allows the cover 114 to be completelyremoved from the structure 118 without requiring physical disconnectionof any other connections between the structure 118 and the cover 114.

FIG. 4 illustrates a more detailed schematic view of the cover removaltool 132. The cover removal tool 132 includes a power distributioncomponent 144 configured to provide the electrical power signal to atransmitter antenna 146. The transmitter antenna 146 is configured to bealigned with the receiver antenna 142 of the cover 114 of FIGS. 2-3B, totransmit the electrical power signal wirelessly from the transmitterantenna 146 to the receiver antenna 142 of the cover 114. The powerdistribution component 144 of the cover removal tool 132 may beconfigured to receive the electrical power signal from an onboardbattery 148, or from another source as is known in the art. The coverremoval tool 132 may also include one or more alignment components 150configured to secure and align the cover removal tool 132 with the cover114 during transmission of the electrical power signal. In this example,the alignment components 150 are magnetic elements configured to alignand secure the cover removal tool 132 to the cover 114 in a mannersufficient to support the cover 114 against the force of gravity. Themagnetic element may be a standalone magnet, or may be a selectivelyactuated electromagnetic element, for example.

Referring now to FIGS. 5A and 5B, a more detailed view of a portion ofthe cover body 116 is illustrated, showing the fastening subassemblies138 changing from the secured mode in FIG. 5A to the unsecured mode inFIG. 5B in response to receiving the electrical power signal from thereceiver antenna 142. Each fastening subassembly 138 in this embodimentincludes a piezoelectric (PZE) element 152 configured to displace inresponse to receiving an electric current, such as the electrical powersignal, therethrough. In FIG. 5A, the PZE elements 152 are in thesecured mode, with an angled engagement surface 154 of each PZE element152 engaging an interior rim 156 of the structure 118. In thisembodiment, the interior rim 156 of the structure 118 has acomplementary angled engagement surface 158 configured to be engaged bythe angled engagement surfaces 154 of the respective PZE elements 152 toinhibit removal of the cover 114 from the structure 118. This allows thecover 114 to be secured to the structure 118 without the need for anyexposed fasteners on the first side 120, e.g., the exterior side, of thecover body 116.

The PZE elements 152 are configured to change from the secured mode tothe unsecured mode by displacing radially inwardly in response toreceiving the electrical power signal therethrough. In this regard, FIG.5B illustrates the PZE elements 152 in the unsecured mode, in which theelectrical power signal is being provided to the PZE elements 152 viathe electrical traces 140. The PZE elements 152 displace inwardly withsufficient displacement to disengage the angled engagement surfaces 154of each PZE element 152 from the complementary angled engagement surface158 of the interior rim 156 of the structure 118. This allows the cover114 to be easily removed from the structure 118. In response to theelectrical power signal being interrupted, e.g., because of removal ordeactivation of the cover removal tool 132, the PZE elements 152 areconfigured to return to their neutral, secured mode.

It should be understood that many other cover configurations may beemployed while retaining these advantages. In this regard, FIG. 6illustrates a hinged cover 160 having a wirelessly actuated fasteningsubassembly 161 according to another embodiment. In this embodiment, thecover 160 includes a cover body 162 configured to be coupled to astructure via one or more hinges 164. The fastening subassembly 161 ismechanically coupled to an interior side 166 of the cover body 162, andincludes an electromechanical actuator 168 and a fastening member 170. Apower distribution component 172 is coupled between the actuator 168 anda receiver antenna 174. The receiver antenna 174 is configured towirelessly receive an electrical power signal from a power source (notshown), such as a cover opening tool similar to the cover removal tool132 of the embodiment of FIGS. 2-5B, for example.

Referring now to FIGS. 7A and 7B, side views of the hinged cover 160 areillustrated, showing the fastening subassembly 161 changing from thesecured mode in FIG. 7A to the unsecured mode in FIG. 7B in response toreceiving the electrical power signal from the receiver antenna 174. Asdiscussed above, the fastening subassembly 161 in this embodimentincludes the actuator 168 configured to actuate the fastening member 170in response to receiving an electric current, such as the electricalpower signal, from the power distribution component 172, which in turnreceives the electrical power signal from the receiver antenna 174. InFIG. 7A, the fastening member 170 is in the secured mode, with thefastening member 170 engaging a structure 176. In this embodiment, thestructure 176 has an exterior surface 178 and an interior surface 180,with the interior surface 180 configured to be engaged by the fasteningmember 170 in the secured mode. The exterior surface 178 of thestructure 176 in this embodiment is configured to form a smoothcontinuous surface with an exterior side 182 of the cover body 162 whenthe cover 160 is closed. This allows the cover 160 to be secured to thestructure 176 without the need for any exposed fasteners on the exteriorside 182 of the cover body 162.

The fastening subassembly 161 is configured to change from the securedmode to the unsecured mode by the actuator 168, which may be anelectromechanical motor, for example, retracting the fastener member 170to facilitate opening the cover body 162 with respect to the structure176, in response to receiving the electrical power signal from thereceiving antenna. In this regard, FIG. 7B illustrates the fasteningsubassembly in the unsecured mode, in which the electrical power signalis being provided to the actuator 168 via the power distributioncomponent 172. The fastening member 170 is retracted by the actuator 168with sufficient displacement to disengage the fastening member 170 fromthe interior surface 180 of the structure 176. This allows the cover 160to be easily opened with respect to the structure 176 via the hinges164.

Referring now to FIGS. 8A and 8B, interior views of a cover 184 in arespective secured mode and unsecured mode are illustrated, according toanother embodiment. In this embodiment, the substantially circular cover184 is configured to matingly engage with a complementary substantiallycircular opening of a structure 186. An interior surface 188 of thecover 184 and an interior surface 190 of the structure 186 areconfigured to secure the cover 184 to the structure 186 via a rotatableactuator mechanism 192. The rotatable actuator mechanism in thisembodiment includes a plurality of hinges 194 each rotatably coupled toa fastening member 196. A distal end 198 of each fastening member 196 isconfigured to matingly engage with a respective receiving member 200coupled to the interior surface 190 of the structure 186 in the securedmode. As shown in FIG. 8B, rotation of the actuator mechanism 192 causesthe fastening members 196 to rotate such that the distal ends 198 of thefastening members 196 are retracted out of the receiving members 200.This rotation and retraction may be facilitated by angled surfaces 202within the receiving members 200. In this embodiment, a receiver antenna204 is disposed on the interior surface 188 of the cover 184, configuredto wirelessly receive an electrical power signal originating outside thecover 184, e.g., from a tool such as the cover removal tool 132 of FIGS.2 and 4. The receiver antenna 204 provides the wirelessly receivedelectrical power signal to a power distribution component, which in turnactuates the rotatable actuator mechanism 192 to retract the distal ends198 of the fastening members 196 from the complementary receivingmembers 200 of the structure 186, thereby changing the rotatableactuator mechanism 192 from the secured mode configured to inhibitopening the cover 184 with respect to the structure 186, to theunsecured mode configured to facilitate opening the cover 184 withrespect to the structure 186.

FIG. 9 is a flowchart diagram of a method 300 of wirelessly actuating acover to change the cover from a secured mode to an unsecured mode,according to an embodiment. The method 300 includes wirelessly providingan electrical power signal to a receiver antenna of a cover body from afirst side of the cover body (FIG. 9, block 302). The method 300 furtherincludes receiving, by a fastening subassembly on a second side of thecover body opposite the first side, the electrical power signal from thereceiver antenna (FIG. 9, block 304). The method 300 further includeschanging, by the fastening subassembly in response to receiving theelectrical power signal from the receiver antenna, from a secured modeconfigured to inhibit opening the cover body with respect to thestructure, to an unsecured mode configured to facilitate opening thecover body with respect to the structure (FIG. 9, block 306).
